Abstract

Procédé et dispositif de pulvérisation hydrostatique en jet rond d'un liquide chargé électrostatiquement. Le dispositif comporte un pulvérisateur classique hydrostatique avec une buse à Vortex 17, alimentée en liquide sous pression. Le jet rond 20 est chargé grâce aux électrodes 12a, 12'a portées à haute tension. Autour du jet pulvérisé 20, on crée un Vortex pneumatique 19, en alimentant en air comprimé la chambre 14b à travers des canaux hélicoïdaux ménagés dans la bague de déflexion 13. Avec des pressions d'air de 3 à 1 bars, on peut réduire la pression de liquide jusqu'à 25 bars, sans q'apparaissent des anomalies de forme du jet. Application à la pulvérisation électrostatique des peintures.
